Switch zoning limitations for Xiotech ISE storage systems

Limitations exist in switch zoning for Storwize® V3500 clustered systems and the Xiotech ISE storage system.

Fabric zoning

To avoid a single point of failure, the Storwize V3500 switch zone must include both target ports from each Xiotech ISE controller.

Target port sharing

Target ports can be shared between the Storwize V3500 system and other hosts.

Host splitting

To avoid the possibility of an interaction between multipathing drivers, a single host cannot be connected to both the Storwize V3500 system and the Xiotech ISE system.

Controller splitting

Xiotech ISE system logical unit numbers (LUNs) that are mapped to the Storwize V3500 system cannot be mapped to other hosts. Xiotech ISE system LUNs that are not mapped to the Storwize V3500 system can be mapped to other hosts.
